FILTER BASES AND SUPRA PERFECT FUNCTIONS
Filter base
Directed toward a set
Closure converges
Closure directed toward
Supra closure converge
Almost supra
converges
Almost supra cluster
Supra compact function
Supra rigid subset
Supra perfect function
We introduce some new generalizations of some definitions which are, supra closure converge to a point, supra closure directed toward a set, almost supra converges to a set, almost supra cluster point, a set supra H-closed relative, supra closure continuous functions, supra weakly continuous functions, supra compact functions, supra rigid a set, almost supra closed functions and supra perfect functions. And we state and prove several results concerning it
